ELEVATOR-SIGNAL.

To all whom it may concern:

Be it known that I, CHARLES A. MoIN- TYRE, a citizen of the United States, residing at Philadelphia, in the county of BhiladeL phia and the State of Pennsylvania, have invented new and useful Improvements in Elevator-Signals, of which the following is a specification.

whereby the operator of the elevator will be notified by suitable signals, such as lights, in a vance of th'e'floor at which he is'to stop, and'l gain just before reaching the stopping place.

' A further object of the invention is to provide an elevator signal whereby the waiting prospective passenger will be notified by suitable signals of the approach of the elevator, say one floor'in advance, an a ain when the elevator reaches the floor on w ich the person is waiting.

' A still further object of the invention is to provide a plurality of ramps arranged in series'and located in the elevator shaft in any convenient position, said ram'ps being electrically connected with diii'erent objects, such as signals'and magnets.

' Another object of the invention is to situate a track adjacent the ramps on *which i'uns'a traveler carrying contact member arranged'in series and adapted to close the circuits at certain times, said traveler being operated by the movement of the elevator either directly or indirectly.

Still another object of the invention-is to provide means 0 erated by the opening of theeleva torsha 1: door to close the circuit through the 'magnets thereby energizing said ma nets, and causing them to brfeal: the circuit t rough tlie'signals previously made.

' A'fiirther obi'ect of the invention is to pro-,

vide the trave er-with two sets of pivoted contact members, oneset of which is caused to c'o act with certain ramps, when the elevator is ascending, while the other set'is caused to -co-'act with certain other ramps.

when' the elevator is descending thellfirst named set th be n em r e tree thei means a; at wer I Specification 0! Letters Patent.

H With these ends in view, this invention consists iii the details of construction and cr imbir'iat'ion of elements hereinafter 'set forth, a'kid then specifically designated by the l-ilalln lsi' i :1

order tha t those skilled in the art to which this invention pertains may understand how to make an use-the same, I will describe its"const ructio in detail, referring b niiiner'als 'tp 'the' accompany'ing drawing f rming' a" part""of"'this application, in

e in igs. l and '3, the elevator shaft is represented by the numeral 2,"having a door 3 at each floor whic is hung inthe ordinary manner, nd provided with 'a-cam bracket 4, foh'af'pu pose to'be' hereinafter described, Within the elevator shaft is situated the elevator car ,5, provided with the ordinary cable 6', ,one'end of whic carries the'coi'interbalancing Iy'veight 7,"sa d cable running'over the o'rdinary'sheave 8, whi'chismounted at the top 05' theelevator shaft. Bower is transilt e, from this"sheave through its 'shajft 9, tli'e pulleylQ thereon, the belt ll, and pulley 12 to the shaft 13 611 which the last named 'p'u ey is'mo'unted. "The s aft '12. and a arshaft' 14 are each prov led with" a greet-vs" ulley it, 911 "whichai e" spirally xjvo'undt e rope or cable16,"each end of said cable having attache 'thertbaweight'fli Said cable s is new ai s the tr veler 1e, w 'ereby motion "s" transmitted from' the shaft 13' to said trave ler, the'weights 17 hold ing th'e able 1,6 that I Hetraveler 18 shown in Figs. 4:, 5 inclu'sive comprises a slide 19, which straddles tion between he-twoslide-"w nibset adapted to be used when the elevator is ascending, and the other set when the elevator is descending, and these bell crank levers are properly insulated from each other, and from the extensions 26 and 27, by

suitable insulating material 34, in the form of sleeves, which surround the pivot members lever carries a contact shoe 36, adapted to coiiperate with the different ramps, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, while the opposite ends project into. the spaces between the pins 21 and 22 and 23 and 24, and when said bell crank levers contact with said pins, the contact shoes 36 are caused to engage or disengage the ra'mps,-depend1ng upon the direction in which the traveler is moved. In orderto prevent the bell crank levers from being moved too far out of engagement with the ramps, I provide pins 61 and 62, one of which is carried by each of the extensions 26 and 27, and against which will rest the bell crank levers when they are moved in the direction whichwill disengage the contact shoes from the ramps.

The arm 25 and the slide 19 are kept in their The toe end of each bell crank relative positions by the strap 63, which is carried by the arm 25, said strap being pro-- vided with a. slot 64, through which passes a retaining bolt or stud 65, the latter being secured to the slide 19.

The action of the traveler is as follows: Referring to Figs. 4 and 5, when the traveleiis moved to the right, the bell crank levers 28 to 30 inclusive will be brought into engagement with the pin 22, causing the contact shoes thereof, to engage the ramps, and this action of the traveler will bring the bell crank levers 31 to 33 inclusive into contact with the pin 24, thereby causing their contact shoes to be disengaged from the ramps. When'the traveleris moved in the opposite direction or toward, the left, of the slide 19, because of the friction between it and the track 20, will stand still and allow the bell crank levers 28 to 30 inclusive, to

engage the pin 21, causing their contact shoes to be disengaged from the ramps, and the same action will cause the bell crank levers 31 to 33 inclusive to engage the pin 23, thus forcing their contact shoes into engagement with the ramps.

It will be noticed that the contact shoes are placed in and out of engagement with the ramps by the action of the pins 21 to 24 inclusive upon the bell crank levers, and as the pins of each pair are some distance apart, the elevator could drift some distance without changing the relation between is preferably in the form of an electrical light bulb, and will be termed for conven-' ience the floor signal. The bell, crank levers 28 and 31 are connected by a common wire 71, which also passes through the flexible conductor, and this wire is attached to the signal 72, in the form of an electrical light bulb, and for convenience'will be termed the advance signal. Thesignals 7O and-72 are connected with the wire 66, which leads to the source of electrical 'energyby a wire 73, which is common to both of said signals.

Adjacent the doors of the elevator shaft are situated signals 74, 75, 76, 77, 78; and 79, preferably in the form of electriclight bulbs, and it'will be noted that only one of these signals is provided for the first and top floors, while the intermediate floors each have 2 of such signals. The signal 74 1s connected by a wire 80 and itsbranches with the ramps 41, 38 and 53 and by a wire 81 with the contact point 82. The signal 75 is connected by a wire 83 and its branches with the ramps 39 and 42, and also by a wire 84 with the contact point 85. The signal 76 is connected by a wire 86 and its branches with the ramps 37, 54, 57 and also by a wire 87 with the contact point 88. The signal 7 is connected by a wire 89 and its branches with the ramps 40, 43 and 60, and by a wire 90 with the contact point 91. The signal 78 is connected by a wire and its branches 92 with the ramps 55, 58 and also by a wire 93 3 The contact points 82, 85, 88, 91, 94 and 3 97 are engaged by the plunger switches 98, 99, 100, 101, 102, 103 respectively, whenever a person signals the elevator operator, thereby partially closing the circuitthrough the line wire 104 to which said switches are con- 3 nected, said line wire leading to the source of electrical energy 67. In order that said plunger switches may be disengaged from their respective contact members, when the elevator shaft is open, I provide magnets 105, 1 06, 107, 108, 109, 110, one of which is ad acent each of the plunger switches,

elevator stops at a floor, and the door of.the

wire 114 with the ramp47. The magnet 109 is connected by a wire 115 with the ramp 51. The magnet 110 is connected by a wire 116 and its branches to the ramps 48 and 52. After the circuit through the magnets have been partially closed by the contact shoes engaging the magnet ramps, said circuits are completed by the opening of the elevator completing the circuit.

shaft doors, because the cam brackets carried by said doors will operate the levers 117, one of which is mounted adjacent each door, and carried by the shaft 118, running across all of the doors of the different ele-.

vator shafts, when they are built in banks. On the shaft 118 is mounted a single connector 1.30, to which is pivoted a rod 119 which carries one or more contact members 120, said contact members co-acting with the magnets for completing the circuit through the line wire 104, to which each of the contact members 120 is connected.

The operation of the device'is as follows: Presuming that a person standing on the third floor wishes to use the elevator which is descending, and the plunger switch 100 has been pressed inward, causin it to co-act with the contact point 88, there y partially As soon as the elevator has descended to a point where the contact shoe of the bell cranklever 32 will come in contact with the ramp v54, which is for the floor light in the descending set of ramps, said circuit will be entirely completed through the source of electrical current 67, a portion of the wire 66, the wire 73, the fioor signal in the elevator, the wire 68, the bell crank lever 32 and its contact shoe, the ramp 54, the branches of the wire 86 leading to said ramp, said wire 86, the.

descending signal 76 on the third floor, the wire 87 to the contact point 88, 'then through the plunger switch 100, and the line wire 104, to the source of electrical energy 67, thus operating the signals 70 and 76 to indicate to the elevator operator that he is to stop at the third floor, and also indicating to the waiting person that the elevator has reached the third floor. The elevator having reached the third floor, it has also caused the contact shoe of the bell crank lever 33 to coact with the ramp 50, partially completing a second circuit and as soon as any one of the elevator shait doors on the third floor is opened, one of the levers 117 will be operated by the cam bracket 4, and cause one of the contact members 120 to engage the magnet 107, thus completing the circuit through the source of electrical energy 67,

. the wire 66, the bell crank lever 33 and its contact shoe, the ramp 50, the wire 113, the magnet 107, its contact 120 and the line wire 104 to the source of electrical energy 67, thereby energizing said magnet 107, causing it to return the plunger switch to its normal open position,,and thereby breaking the first named circuit, causing the signal lights to be extinguished. The position of the elevator at the third floor has also caused a third circuit to be partially closed by the cooperation of the contact shoe of the bell crank lever 31 with the ramp 58, and if a person waiting upon the second floor has closed the down plunger switch 102, then a circuit will be completed through the source of electrical energy 67, a portion of the wire 66, the wire 73, the advance'signal 72, the wire 71, the bell crank lever 31 and its contact shoe, the ramp 58, the branch of the wire 92 leading from said ramp, said wire '92, the descending signal 78 on the second floor, the wire 93, the contact 94, the plunger switch 102 and the line wire 104 to the source of electrical energy 67, thus caus ing the signals 72 and 78 to be operated, indicating to the operator of the elevator that he is to stop at the next or advance floor,

and also indicating to the waiting person that the -elevatoris approaching. This same operation takes place at any, and all floois. It is to be understood that the same signal light on the floor indicates when the elevator is approaching, and when it reaches the floor. hen the elevator is ascending, the contact shoes of the bell crank levers 31 to 33 inclusive, will be disengaged from their ramps, as hereinbefore described, and the contact shoes of the ball crank levers 28 to 30 inclusive will. be caused to engage their respective ramps, which is the ascending set, so that the different signals may be given in the same manner as hereinbefore described, except that the circuit will be completed through other wires, and the upward indicating signals or lamps on the different floors. When a person standing on the top floor signals for the elevator, and said elevator is ascending, a signal will be shown in the advance light 72 in the elevator, when the latter reaches the next to the top floor, here shown as the third floor, and will also show a signal on the top or fourth floor by the light 74, because the contact shoe of the bell crank lever 28 is in contact with the ramp 38, and as the elevator ascends to the top or fourth floor the signal lamp 74 will indicate that the elevator is at that floor, because the contact shoe of the bell crank lever 2-9 will then be in contact with fied form of my invention in which theramps are situated longitudinal of the elevator shaft, and the different ramps are located adjacent the floors, so that the circuits are completed at the floor which the elecombination with a plurality of ramps 10 V vator is to stop at, and again at the floor in advance to that floor at which the elevator is to stop. These ramps are similar to those hereinbefore described, except that they would be of'greater length, since that contact shoes of the bell crank levers must travel a greater distance for the traveler to which said bell crank levers are pivoted is attached directly to the elevator. In this form of the invention the ramps will be numbered, the same as first used in my preferred form, and the wires running from said ramps to the signals on the floors of the building will also contain the same numbers as hereinbefore used for such wires, the only difference being in the numbering of the wires running from the flexible conductor 69, whichinthis case contains only the wire 73. The wire 73 is connected with a'rosette 121 in the elevator and from this rosette leads a wire 122 to the bell on k levers 30 and 33,'while a second wire 12 leads from the rosette to the si al 70 in the elevator, and from said signal a nother wire 124: leads to the bell crank levers 29 and 32, and still another Wire 1255 leads from the rosette to the signal 72 in the elevator, which is connected by a wire and its branch 126 with the bell crank levers 28 and 81, so that the diflimits of the appended claims without departing from the spirit of my invention.

Having thus fully described myinvention, what I claim as new and useful, is-

l The combination with an elevator car, its actuating mechanism, two sets-of signaling devices, one for ascending and descending cars, located outside of the elevator shaft and a floor and advance signals located within the car, of a plurality of ramps located within the shaft, forming a portion of the signaling circuits insulated from each other and from the ground, said ramps'being divided into a descending set and an ascending set, a traveler operated by the elevator car, andcomprising a slide an arm coupled to said slide, and movably independent of said slide within certain liming circuits, and means carried by the slide for contacting with the bell crank levers to cause one set of contact shoes to be disengaged from their ramps and simultaneously Y cause the other set of contact shoes toen gage their respective ramps. i
